цены на них продолжают снижаться. И при этом для двухмерного телевизора вам не нужно покупать никаких дополнительных аксессуаров. С другой стороны, с 3D телевизором вы получаете новейшую технологию высокого разрешения, которая сделает намного выразительнее изображение даже для традиционного двухмерного материала.

3D телевизор и активные очки – это только часть проблемы, не менее важна и доступность трехмерных программ и фильмов. Ограниченный выбор фильмов и другого видеоконтента в 3D формате – основная проблема 3D ТВ на сегодняшний день.

Tele and web conferencing

In the past few years, corporations have become bigger and more spread out. That’s why teleconferencing – the real-time exchange of information between people who are not in the same physical space – has become such a big industry. Through teleconferencing, companies can conduct meetings, customer briefs, training, demonstrations and workshops by phone, television or computer or online instead of in person.

The simplest phone teleconference is a three-way call, available in many homes as a service from the telephone company. Another very simple (but not necessarily effective) method is to have two groups of people talk to one another via speakerphone. The limits of three-way calling and the sound quality of speakerphones make both of these options impractical for most businesses.

Conference calls let groups of people – from a few to hundreds – communicate by phone. Banks and brokerages often use conference calls to give status reports to large numbers of listeners. Other businesses use conference calls to help coworkers communicate, plan and brainstorm. To connect to the call, attendees call a designated number (MeetMe conferencing), or an operator or moderator calls each participant (ad hoc conferencing).

Conference calls connect people through a conference bridge, which is essentially a server that acts like a telephone and can answer multiple calls simultaneously. Software plays a large role in the bridge’s capabilities beyond simply connecting multiple callers. Companies using Voice over IP (VoIP) telephones can also host conference calls themselves if the VoIP software supports them. Many phone conferencing systems require a login and personal identification number (PIN) to access the system. This helps protect confidential and proprietary information during the call. Video phones can add a visual element to conference calls, but businesses often need to share other visual information.

Web conferencing

Web conferencing allows people to communicate through text and video in addition to audio. The simplest web conferencing methods use chat and instant messaging programs to host text-based group discussions. More

sophisticated programs exchange visual information with webcams and streaming video. Some allow people to share documents online.

Companies can either purchase conferencing software and host their meetings themselves or use a hosting service. Hosting services provide the software and server space on which to conduct meetings. Either way, the company or the hosting service must have software to coordinate the meeting and ample server space and bandwidth to accommodate it.

Web conferencing programs combine tools already common to web pages and Internet communication. They bundle these tools into one interface to create an interactive meeting environment. These tools include:

•HTML, XML and ASP markup

•Java scripts

•Flash animation

•Instant messaging

•Streaming audio and video

Some programs are entirely computerand Internet-based. Others use the telephone system to distribute audio content. To participate in the online meetings, participants must have:

•A computer/television

•An Internet connection

•A telephone, if audio content is not provided online

If the conferencing program relies on Internet-based audio chat and webcam feeds, the participants’ PCs should have:

•Microphones

•Webcams

•Video capture cards

Web conferences aren’t just for businesses. Hospitals can use audio and video conferencing to supplement their emergency room staff. For example, some Massachusetts hospitals use video conferencing to allow neurologists to confer with stroke patients. Web conferencing has also allowed deployed soldiers to communicate with their families and even get married.

Web conferencing programs come with a tremendous variety of features and capabilities. Some can merge with a company’s existing e-mail, calendar, messaging and office productivity applications. Some allow attendees to view the presentation in their regular web browser without installing any additional software. Depending on the software, people can:

• View slide presentations from programs like PowerPoint

74

•Draw or write on a common whiteboard by using their computer mice or typing

•Annotate images and diagrams using the same whiteboard principle

•Transmit still pictures or video to other attendees via a webcam (This increases the required bandwidth and can sometimes slow the transfer of the presentation.)

•View information from the moderator’s computer desktop using screen sharing

•Share documents, often even if attendees don’t have the software that created them, using application sharing

•Hold interactive question-and-answer sessions that integrate video and audio

•Send public or private messages through instant messaging

•Annotate or modify documents and spreadsheets from compatible applications

•Transfer files between attendees

•Ask and answer questions through audio chat (as an integrated part of the software) or by phone.

Since these meetings take place over the Internet, programs include options for security and encryption. Most programs require moderators and attendees to use a login name and password to access the meeting. Some use SSL or TLS encryption to protect data. Some companies also host web conferences on internal servers so that the data stays behind the corporate firewall. The moderator or host can monitor who is participating in the conference through sign-in logs and roll calls.
